Manufacturer, Supplier & Exporter of Inconel 625 Round Bar
Inconel 625 Round Bar is a high-performance nickel-chromium-molybdenum alloy (UNS N06625 / Alloy 625) known for its exceptional strength, corrosion resistance, and thermal stability. Manufactured by Riddhi Siddhi Impex and supplied across India, it is designed to withstand extreme environments, making it suitable for industries such as chemical processing, marine, aerospace, and power generation. As a round bar, it is commonly used in shafts, fasteners, structural components, and critical parts requiring superior durability..
RThe alloy’s unique properties stem from its carefully engineered chemical composition. Inconel 625 typically contains ≥58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium + tantalum, with minor iron, carbon, manganese, silicon, aluminum, and titanium. This composition ensures solid-solution strengthening, excellent resistance to pitting and crevice corrosion, and the ability to maintain mechanical integrity in both high-temperature and chloride-rich environments..
Inconel 625 Round Bar exhibits outstanding mechanical properties. Its tensile strength ranges up to 930 MPa, with yield strength between 414–517 MPa depending on size and temper. Elongation values are typically ≥30%, ensuring high ductility. The alloy also demonstrates excellent hardness, impact resistance, and long-term stability at elevated temperatures. These mechanical characteristics make it ideal for applications that demand both strength and corrosion resistance under severe conditions..
The alloy maintains its performance across a broad temperature range, from cryogenic to elevated temperatures exceeding 1000°C. Its density is approximately 8.4 g/cm³, and it exhibits a melting range of 1290–1350°C. This thermal stability, combined with oxidation and corrosion resistance, allows Inconel 625 round bars to be used in high-temperature chemical reactors, furnace components, and heat exchangers without risk of material degradation...
Inconel 625 round bars are available in various diameters, typically ranging from 3 mm to 800 mm, with commonly stocked sizes between 10 mm and 200 mm. Standard lengths range from 250 mm to 3000 mm or more, with options for cut-to-length, hot-rolled, cold-drawn, centerless ground, and precision-machined finishes. Suppliers like Riddhi Siddhi Impex provide customization for both surface finish and dimensions to meet the specific requirements of industrial applications..
